Abstract (en)
[origin: EP0945664A2] The present invention relates to a synthetic resin-made fastening-limiting device employed for limiting a fastening force of a fastening member in case of fastening a connection portion between a pipe receiving port of the joint and a pipe by means of the fastening member. In the fastening-limiting device according to the present invention, an appropriate sealing property of the pipe connection portion and a screw amount of the fastening member required in trying to preventing the pipe from slipping off can be surely determined. Furthermore, the operator can recognize easily the appropriate screw amount of the fastening member by a sound and a touch. This fastening-limiting device has a ring portion 21 fittable onto the pipe receiving port 10 of the joint A and a protrusion 26 disposed on the ring portion 21. On a side of one end in an axial direction of the ring portion 21, a first abutting portion 22 is formed. On a side of the other end in an axial direction of the ring portion 21, a second abutting portion 23 is formed. A gap a between the first abutting portion 22 and the second abutting portion 23 is equal to a distance between a reference face 130 and a confronting portion 121 in a state wherein the fastening member 120 exhibits functions such as sealing property and prevention of slipping-off. On either side of the protrusion 26, recessed portions 27 and 28 are formed, and projections 113 are disposed on a side of the joint. <IMAGE>
